The number of games released each year is holding steady at about 3200.

Rating inflation continues since last year, but it seems to be slowing down.

Games that were highly underrated in 2011 were overrated in 2012, as BGG users overcompensated for their former low ratings. Games that were highly overrated in 2012 were still overrated in 2013--these were highly hyped games and the hype is still dying down.

If you go to the main page, you can download an amazing 17-megabyte JSON dump of BGG data I've compiled. It includes descriptions and genres for every game in the dataset, and three data samples that convey historical rating data over three years. At this point I feel like I'm adding enough on top of what the BGG API can give you (the historical rating data) that I can make the data dump available without apology.
